What do you expect anyone to do based on this data??? For all I
know someone in another room is turning off a switch every couple
hours :)

So if you want to report a problem, put yourself in the place of
the engineer who has to fix it, what would you want... well, how
about hardware description, pci config, log file output, I dont
know, something that would give me a chance of knowing what
the problem is.
